Answer:
This question is incomplete, the complete question is;
A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)
A) The surface area is increasing at the rate of 28pi square mm per second.
B) The surface area is decreasing at the rate of 28pi square mm per second.
C) The surface area is increasing at the rate if 32pi square mm per second.
D) The surface area is decreasing at the rate of 32pi square mm per second.
Answer:
Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
Explanation:
Given the data in the question;
let r be the radius and h be the height of the tube
so volume V = πr²h
dv/dt = πr² dh/dt + 2nrh dr/dt
⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt
⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2
Area Surface S = 2nrh
ds/dt = 2π ( r.dh/dt + h.dr/dt )
= 2π ( 6×2 + 2)
= 2π (14)
= 28π
therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
What is the value of x in the equation 2 (6 x 4) minus 6 2 x = 3 (4 x 3) 1? 1 3 4 6.
Answer:
4
Step-by-step explanation:
2 (6 x + 4) - 6 + 2 x = 3 (4 x + 3) + 1
12x + 8 - 6 + 2x = 12x + 9 + 1
12x + 2 + 2x = 12x + 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 4

Answer:
Roads, hospitals, and monuments were built.
Buddhism spread through missionary monks.
Explanation:
Asoka was the founder of the Moorish dynasty, and extended the kingdom to the western half of northern India. His endeavor, accompanied by fearsome bloodshed, provoked profound spiritual upheavals at Asoka, after which he embraced Buddhism, which had appeared in Magadha two centuries earlier. Since then, the cruel Asoka has become known as the godly Asoka. In the words of the emperor himself, since then his sound was no longer booming, but the voice of dharma.
During his rule, he pursued an official policy of non-violence. The unnecessary killing and mutilation of animals has been abandoned, such as hunting for hunting and stamping.
Asoka also showed mercy to the captives, allowing them a day of freedom each year, and providing ordinary citizens with free education at universities. He treated subjects as equals regardless of religion, politics or caste and made free hospitals for both humans and animals. Asoka defined the main principles of nonviolence, tolerance of sects and opinions, obedience to parents, respect for teachers and priests, human treatment of servants (slavery did not even exist in India at that time) and generosity to all. These reforms are described by Asoka's edicts.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? The first law describes how thermal energy is conserved but not the direction it moves. The first law describes the direction thermal energy moves but not how it is conserved. The first law describes how thermal energy can be created but not how it can be destroyed. The first law describes how thermal energy can be destroyed but not how it can be created.
The statement which best describes the difference between the first law of thermodynamics in comparison with the second law of thermodynamics is that: A. The first law describes how thermal energy is conserved but not the direction it moves.
The First Law of Thermodynamics states that energy can neither be created nor destroyed but it can only be transformed (converted) from one form to another such as potential energy to kinetic energy. Thus, thermal energy is always conserved according to the First Law of Thermodynamics.
On the other hand, the Second Law of Thermodynamics states that the entropy (disorderliness) of an isolated system always increases and can never be decreased. Thus, the direction of an energy is described by the Second Law of Thermodynamics.
In conclusion, the difference between the First Law of Thermodynamics in comparison with the Second Law of Thermodynamics is that the first law describes how thermal energy is conserved but not the direction in which thermal energy moves.

Using a t-distribution table or a t-critical value calculator, the critical value for a one- tailed t - test for the sample given at 0.05 α-level would be 1.833
The critical value for a one-tailed, paired sample t test can be defined thus :
[tex]t_{critical} = t_{α, df-1} [/tex] Sample size, n = 10The degree of freedom , df for a 1 - tailed t-test is calculated using the relation :
df = n - 1Hence,
Degree of freedom, df = n - 1 = 10 - 1 = 9
Using a Tcritical value calculator or a t - distribution table :
[tex]t_{critical} = t_{0.05, 9} = 1.833 [/tex]
Therefore, the critical value for a one - tailed test at 0 05 level of confidence would be 1.833.
